Eddy-Current Probe Scaling and Rotor Dynamics Processing
The Bently Nevada 3300/16-13-01-02-00-00-00 processes dynamic signals from eddy-current proximity probe systems and converts displacement signals into vibration and shaft position values. The monitor applies configured probe scaling to maintain measurement accuracy for the 3300 Proximitor Sensor interface.
In addition, the module evaluates rotor dynamic behavior through X/Y vibration channel monitoring. Therefore, it allows operators to analyze shaft movement, mechanical imbalance, misalignment effects, and changing rotor conditions.
The gap channel validates probe operating conditions by monitoring the DC gap voltage. During field commissioning, technicians typically verify probe gap voltage near the recommended -10 VDC target range to confirm correct probe positioning and signal integrity.
The monitor also performs signal conditioning and alarm processing to reduce measurement interference. As a result, the module supports continuous machinery protection functions within the 3300 rack architecture.
Frequently Asked Questions
Q: What type of input signal does the 3300/16-13-01-02-00-00-00 accept?
A: The module accepts signals from Bently Nevada eddy-current proximity probe systems through compatible 3300 Proximitor Sensor interfaces.
Q: Does the 3300/16-13-01-02-00-00-00 measure both vibration and shaft position?
A: Yes. The module measures two radial vibration channels and monitors average shaft position through gap voltage measurement.
Q: Is the module hot-swappable in the 3300 rack system?
A: Installation or removal should follow Bently Nevada rack maintenance procedures. Technicians must verify rack power conditions and wiring status before replacement.
Field Installation Guidelines
- Install the module into the designated Bently Nevada 3300 rack slot and verify rack power compatibility before operation.
- Connect proximity probe wiring according to the specified shielding and grounding requirements to reduce electrical noise.
- Confirm eddy-current probe scaling parameters match the installed Proximitor Sensor configuration.
- Verify probe gap voltage during commissioning and adjust probe position to achieve the expected operating range.
- Check X/Y vibration channel polarity, signal direction, and alarm setpoints before connecting machinery protection logic.
- Separate probe signal cables from high-current power cables to minimize electromagnetic interference.
